SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyze an unfamiliar codebase and generate a structured onboarding guide with architecture map, key entry points, conventions, and a starter CLAUDE.md. Use when joining a new project or setting up Claude Code for the first time in a repo.

Core Features & Use Cases

  • Reconnaissance and structure mapping to avoid reading every file
  • Architecture mapping and entry-point identification
  • Generated starter CLAUDE.md and reusable onboarding artifacts
  • Use cases: joining a new project, setting up Claude Code, documenting a repo for future hires

Quick Start

Run the onboarding workflow on the target repository to generate the guide and starter CLAUDE.md.

FAQPage Schema
How do I generate a codebase onboarding guide for a new project?

Generate a codebase onboarding guide by analyzing the repository structure, package manifests, and frameworks to produce architecture maps, key entry points, and a starter CLAUDE.md. This avoids reading every file manually and accelerates project ramp-up.

What is the best way to map architecture and entry points in an unfamiliar codebase?

Mapping architecture in an unfamiliar codebase involves detecting project structure and package manifests to identify key entry points and conventions. This reconnaissance approach generates structured guidance without manually reading every source file.

How do I set up Claude Code in a new repository?

Set up Claude Code by running an onboarding workflow that analyzes the target repository to generate a starter CLAUDE.md. This artifact captures project conventions, architecture, and entry points to guide future AI-assisted development.

Can I generate developer onboarding documentation without reading every file?

Generate developer onboarding documentation without reading every file by scanning the codebase to detect frameworks, package manifests, and structural patterns. This produces a structured guide with architecture maps and reusable starter artifacts.

Does codebase onboarding work for any project structure or framework?

Codebase onboarding works across various project structures by detecting package manifests and frameworks to map the architecture. It generates structured guidance and starter artifacts applicable to any repository requiring developer ramp-up documentation.

What limitations exist when generating a starter CLAUDE.md from an existing codebase?

Generating a starter CLAUDE.md relies on detecting package manifests and structural patterns, so heavily obfuscated or non-standard project structures may produce less accurate architecture maps and require manual refinement of the onboarding artifacts.
